This story has been widely under-reported and the impact is potentially huge. My beef with MS is this: the keys were leaked in 2021 and were still signing authentication tokens in 2023, but there's not a single Azure service that allows me to enter credentials with a 2 years duration. It's a classic case of "do as I say, not as I do".

This. They don’t even use a HSM if I understood correctly and using one is not part of the mitigation plan. Not OK.

When I worked at Microsoft, I found a case internally where it appeared that a service was accepting expired certificates as a form of authentication for admin-level calls. I was fairly new, so I brought it to someone who had been at Microsoft for the better part of a decade. We didn't own the service in question, and he told me that, since it wasn't our service, I should just focus on continuing our work, and that it wasn't our responsibility to raise the security concern.

In the end, it turns out it was not accepting expired certs -- there was another auth method superseding the certs -- but the behaviour I saw in this case was not unusual to encounter.

Microsoft has many excellent engineers, even in security. But decades of culture rot take longer than a few years to fix, and a lot of old-timer Microsofties have this "not my problem" viewpoint that can lead to major security risks. No doubt, the way Microsoft has handled this year's layoffs -- staggered, leaving people in the lurch and in serious stress for months on end -- has wiped out much of the progress they've made under Satya.

tl;dr I'm not surprised by (a) Microsoft having breaches and (b) Microsoft not dealing with security issues in a timely manner.

This seems overly hyperbolic and alarmist. I do not think the sources prove the scope of breach the post asserts ("all of Microsoft"), seems more like a temporary key leak that was subsequently revoked.

You should be. HN buried Mastodon as a viable social media platform a year ago.

Earlier quoted context omitted.

These problems are specific to Microsoft though; outside of service outages and customer misconfiguration, AWS and GCP don't have a history of such incidents.

Was the Capital One breach not a result of gross internal malpractice on the part of Amazon? That allowed an Amazon employee to gain priviledged access to CC data in Capital One's environment.

There are multiple analysis of that breach available. Pick one.

Here’s a starter.

Give it a few years and then on-prem hardware and simple server hosting will become fashionable again.

On-prem is very expensive compared to cloud.

For on-prem or cloud, you need some engineers (either SRE or SysEng) to handle your hosting infrastructure. So, not much difference in cost there. Then, there is all of that compute. Currently, an AMD EPYC 7551 system can be put together for about $2.2K USD. That’s 64 threads, 256GB of RAM, redundant 2TB NVMe in RAID1, plus chassis, power and such. The equivalent amount of compute being available 24/7 is going to be extremely pricey over time.

My current employer handles things where internal service at the org are on-prem while customer facing services are cloud. Even the cloud stuff backs up to an on-prem storage system (though it also gets backed up to an off-site S3 provider).

The worst part of the story to me is —- those were not even the right keys, those were something issued to a client and scoped, but scoping check was broken. It’s unbelievably bad all around

This is clearly an overreaction. Cloud will be fine.

He defeats Sephiroth at the end of the game. Maybe he'll defeat Microsoft too.

Typical JRPG. Start with saving a cat, end with fighting Microsoft.

People fled from mainframes, now they are flocking to cloud...

People fled from mainframes to client server. Running a Windows Server with BackOffice in their IT department and having Windows clients. Now they are flocking to the cloud.

I remember when the Network Computer was going to put Microsoft out of business. It was Sun providing the NC and JavaOS, Netscape providing the Web Browser and anyone who wanted to license the NC to make their own. Internet was too slow then as everything was stored on the Internet, which because the Cloud model. Microsoft bundled IE with Windows to destroy Netscape and made Dotnet destroy Java.

This is embarrassing for Microsoft. All their cloud services have been hacked. Data has been leaked. Could lead to lawsuits.

On-prem hardware may become fashionable but simple server hosting most likely not. If it ever becomes fashionable then most likely it will be some form of container (or Kata Container) orchestrator on top of on premise hardware.

Also even for softwares deployed on on-prem hardware, big orgs will still need single sign on, which will still be open to these kind of attacks.
